The printer head is a printer component that helps to transfer the ink on the page. When the nozzles get clogged, the prints appear streaky or faded. Sometimes periodically, small amounts of ink or dust dry up and get collected in the nozzle. Spotty, streaky or faint are all common signs of a clog that can return to working condition if you clean the HP print head. It generally happens when you stop printing for some time, the cartridge will get dry at the end, and you need to replace them.
